Answer: A. 20 is the answer.
Step-by-step explanation:
x+40 = 3x
or, 40 = 3x-x
or, 2x = 40
or, x = 40/2
so, x = 20
Answer:
The longer diagonal has a length of 7.3 meters.
The angles are 31.65° and 18.35°
Step-by-step explanation:
If one angle of the parallelogram is 50°, another angle is also 50° and the other two angles are the supplement of this angle. so the other three angles are:
50°, 130° and 130°.
The longer diagonal will be the one opposite to the bigger angle (130°), and this diagonal divides the parallelogram in two triangles.
Using the law of cosines in one of these two triangles, we have:




So the longer diagonal has a length of 7.3 meters.
To find the angles that this diagonal forms with the sides, we can use the law of sines:





The other angle is B = 50 - 31.65 = 18.35°

Answer:
1,078
Step-by-step explanation:
I got that answer by multiplying 22 and 49. We know that product means to use the multiplication operation so our problem would look like this:
22 * 49 = 1,078
Answer:
0.14204545454545
It's a repeating decimal
Step-by-step explanation:
25/176 is the same as 25 ÷ 176
so 25 ÷ 176 = 0.14204545454545
and it is a repeating decimal because the reminder is not 0
